A Picture is Worth... UNEP's Atlas of Our Changing Environment

Brought to you by the magic of Google Earth/Maps and the UN: the United Nations Environmental Program's (UNEP) stunning world atlas of the changing environment. The interactive atlas allows you to toggle through a dizzying array of satellite images and ground photos showing the impacts of anthropogenic activities and climate change on the global environment over the last 3 decades.

The area of forest allocated to logging activities in Gabon has surged from less than 10 percent to more than 50 percent over the last 4 decades, with most of the increase taking place over the past decade. According to UNEP's database:

"The 2000 image shows a clear cut patch in the centre of the image at a regrowth stage. This is in contrast to the 1988 image, in which only slight disturbance of the forest cover is visible (yellow arrow). The least densely populated country in Central Africa, Gabon has less pressure than many of its neighbours to convert forests to agricultural land. With good forest management practices, the immense value of Gabon’s Guineo-Congolese forest can be sustainably utilized for many generations."

Not the most uplifting set of images (by any stretch of the mind), but a valuable resource that should help people gain a better grasp of the enormous impact humanity has exerted on the planet in less than half a century.
